Optomechanical damping of a microcantilever force sensor in liquid [PDF]

open access: yes, 2010
A new instrument, constant deflection atomic force microscopy (CD-AFM) constructed to perform force spectroscopy measurements without mechanical instabilities associated with the use of soft AFM cantilevers has been developed, tested and calibrated ...

The FM/AFM bilayer Bethe lattice with FM or AFM interlayer interactions

open access: yesphysica status solidi (b), 2008
AbstractThe bilayer Bethe lattice with the Ising spins of the top layer having only ferromagnetic (FM) interactions and the spins of the bottom one having only antiferromagnetic (AFM) interactions were allowed to interact via the interlayer interaction either FM or AFM type.

Interfacial Modulation for High‐Efficiency Large‐Area Organic Photovoltaics and Perovskite‐Organic Tandem Solar Modules

open access: yesAdvanced Functional Materials, EarlyView.
Self‐assembled monolayers (SAMs) are promising hole‐transporting materials for organic photovoltaics (OPVs), but suffer from self‐aggregation and poor large‐area uniformity. We find that interfacial modification using nicotinic hydrazide can eliminate the residual SAM aggregates by forming energetically favorable complexes, yielding uniform SAM.

Participation of {1 0 0} Slip System in Sliding Friction at (0 0 1), (1 1 1) and (1 1 0) Surfaces of Fluorite (CaF2) Crystal

open access: yesTribology Online, 2012
Indentation experiments and friction measurements were performed at three low index faces of fluorite (CaF2) crystal. Deformation patterns were analyzed by observing step structures with atomic force microscopy (AFM). Upon indentation at (0 0 1) surface,

Omnipolar Magnetic Field Detection by Superlattice‐Based Hall Sensor

open access: yesAdvanced Functional Materials, EarlyView.
Magnetic‐field‐induced electronic switching is demonstrated in unit‐cell‐engineered La0.7Sr0.3MnO3–BiFeO3 superlattices. Distinct substrate terminations modify magnetic and transport properties. Hall resistance measurements show omnipolar, hysteretic anomalous Hall switching above the Curie temperature, arising from Fe─Mn interfacial exchange, enabling

Treatment efficiency of effluent prawn culture by wetland with floating aquatic macrophytes arranged in series

open access: yesBrazilian Journal of Biology
The efficiency of a series of wetland colonized with Eichhornia crassipes and Salvinia molesta to treat the effluent of a giant river prawn (Macrobrachium rosenbergii) broodstock pond was evaluated in this study.
